Puberty Growth Peak

Understand the stages of the adolescent growth spurt.

Stage 1: Pre-Spurt

Typical Age: 8-11. Growth is steady but slow before the major acceleration.

Stage 2: Spurt Initiation

Initial acceleration. Increased metabolic activity and nutritional needs.

Stage 3: Peak Height Velocity (PHV)

The fastest growth period. Boys can grow 10cm/year, girls 9cm/year.

Stage 4: Deceleration

Growth slowing down as the skeleton matures and growth plates start to close.

Stage 5: Final Adult Stature

Full skeletal maturity. Minimal to no growth after this point.

Critical Support during PHV

Peak Height Velocity (PHV) is the period of the most intense growth during puberty. During this time, your child's body needs extra support:

Calcium & Vitamin D

Essential for rapid bone mineralization and strength.

Increased Sleep

Growth hormone is primarily released during deep sleep.
